【摘要】 对计算疲劳强度可靠性的经典算法———递推法做了进一步推导,得出了各级应力循环造成的累积损伤度和失效概率之间的计算公式。与原算法相比,新公式具有意义简明、运算快捷的特点。实例计算检验表明,两者计算出的失效概率结果完全相等。更多还原

【Abstract】 The improvement for the classical recurrence method of fatigue strength reliability was disscussed.The computational formulae for accumulation damage degree and invalidation probability caused by different stress level was presented.Comparing with the existing method,the present method has the advantages of the conciseness and fast computation.The numerical tests show that the invalidation probability obtained by the present method is equal to those obtained by the existing method.更多还原
